Pakon ===== Pakon is a parental control system and network traffic filter. It allows flexible configuration and wide range of detection. It actually filters the traffic, unlike most other parental control systems that simply block DNS queries. Pakon-guts ---------- This is the backend part that does the heavy lifting. It connects to a nfqueue and filters the packets (routing them to the nfqueue is a task for iptables). It is configured through lua files. It exports the active flows through a unix domain socket. Compilation ----------- First, initalize the build system: git submodule init git submodule update Then install all relevant dependencies and their headers: - Netfilter queue - lua 5.1 Then compile: make RELEASE=1 MAX_LOG_LEVEL=DBG Running ------- You can get inspired by the `launch` script. You need to set up iptables to pass the relevant traffic to it through NF QUEUE. Then you need to pass the configuration in a lua file. You can also specify how much is logged, through the environment variables `PAKOND_STDERR_LEVEL` and `PAKOND_SYSLOG_LEVEL`. These specify which severity (and more severe) is logged to stderr and syslog respectively. The levels are: - TRACE - DBG - INFO - WARN - ERROR - FATAL Note that what is logged is also limited by what logging is compiled in with the `MAX_LOG_LEVEL` make option above. Furthermore, it is possible to enable an internal logging ringbuffer. If you run with `PAKOND_RINGLOG=yes` environment variable, all the messages (even the ones that are not output) are stored for some time and they are dumped in case a problem happens. It is recommended to do so when trying to debug a problem.
The backend part of the Pakon (Parental Control for Turris routers) which communicates with the kernel and decides if packets could be passed on.
